The assessment calculated risk by aggregating the potential number of millions of people affected by five scenarios: storms, storm surges, river floods, earthquakes and tsunamis. With a “high score” of 57.1, the area has almost twice as many people at risk as second-placed Manila, which scored 34.6. China’s Pearl-River Delta (which includes Hong Kong, Macau and Guangzhou) was third with 34.5, and Osaka-Kobe was fourth with 32.1. Chalk another win up to Tokyo over Osaka! Sort of.

Scores here are measured by the rather heartless-sounding “Value of working days lost” (via: Mind the Risk)

It’s important to note that these results are skewed by Tokyo and Yokohama’s nation-sized population and therefore gives us an indication the size of potential disasters, rather than a score reflecting the danger of living there for each individual. Still, best prepare your emergency torch, bottled water and poop bag now.
